Answer:
60 : 28, 90 : 42, 120 : 56, 150 : 70
here are some of the ratios equivalent to 30:14
give me brainliest please
multiple 30:14 or divide it by 2 to get the equivalent
[ 2x + y = -9 ] x -3
[- 3x +11= y ] x 2
-6x -3y = 27
-6x + 22 = 2y
-6x +27 = 3y
-6x +22 = 2y
5 = y
-6x -3x5 = 27
-6x -15 = 27
-6x = 42
-x = 42/6
-x = 7
x = -7
answer
x = -7
y = 5
Answer:

The correct answer is C
Step-by-step explanation:
d=√((x_2-x_1)²+(y_2-y_1)²)
=(−1−2)2+(4−3)2‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾√
=(−3)2+(1)2‾‾‾‾‾‾‾‾‾‾‾‾√
=9+1‾‾‾‾‾√
=1‾√0
=3.162278
For each of the ordered pairs, the x coordinate is squared to find y.
x = 1
1^2 = 1
x = 2
2^2 = 4
x = 3
3^2 = 9
x = 4
4^2 = 16
